-  * `sudo udevmonitor -e` ... this should be run for any problems when a device is plugged in, or removed.  It will output UEVENT blocks for the event from the kernel, and a following UDEV block; these are timestamped so you know how long it takes to process.  The UDEV block contains more information, which udev adds through various helper programs.
+  * `sudo udevadm monitor -e` ... this should be run for any problems when a device is plugged in, or removed.  It will output UEVENT blocks for the event from the kernel, and a following UDEV block; these are timestamped so you know how long it takes to process.  The UDEV block contains more information, which udev adds through various helper programs.
-   * ''note that in Ubuntu 8.10, the udevmonitor command has been replaced with the "udevadm monitor" command. This changes the above command to'' `sudo udevadm monitor --e`
  
   * `/var/log/udev`, this is the output from above for the boot process.  Especially note whether a UDEV block takes a long amount of time to appear, or doesn't appear at all.
